Seedling emergence and growth of sugarbeets as influenced by surface and incorporation applications of petroleum mulches

Isabgol (Plantago ovata Forsk) seed germination and emergence as affected by environmental factors and planting depth

Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...

Influence of environmental factors on Cucumis melo L. var. agrestis Naud. seed germination and seedling emergence

Cucumis melo L. var. agrestis Naud. (field muskmelon) is an annual invasive weed in many parts of Asia. However, there is very little available information about the germination and emergence of this species. Therefore, laboratory experiments were conducted to evaluate the effects of light, temperature, salt stress, osmotic stress, pH, and depth of planting on field muskmelon germination and se...

Factors affecting Campsis radicans seed germination and seedling emergence

Krishna N. Reddy Southern Weed Science Research Unit, USDA-ARS, P.O. Box 350, Stoneville, MS 38776 The effects of environmental factors on germination and emergence of Campsis radicans seeds were examined in laboratory and greenhouse experiments. Campsis radicans pods produced numerous, papery, and small seeds (696 seeds/pod; 4 mg/seed). Seeds exhibited dormancy that was relieved (74% germinati...

Seed viability, germination and seedling growth of canola (Brassica napus L.) as influenced by chemical mutagens

Mutation induction is considered as an effective way to enrich plant genetic variation, particularly for traits with a very low level of genetic variation. The objectives of this study were to evaluate the effect of different dosages of chemical mutagens on seed germination, seed viability and seedling growth characteristics and to identify optimum treatment conditions for chemical mutagens bas...
